The term "mental rotation" refers to a mental process during which individuals "encode the spatial information into an image, rotate the image mentally, and then access the image in its new orientation." Spatial perspective taking is based on a mental rotation process of the self. In spatial perspective taking, individuals seem to rotate themselves mentally into others' orientation to adopt their spatial perspective. The aims of the study presented here were to examine the mental rotation ability of individuals with visual impairments and the effect of visual status, gender, and chronological age on this ability. For this purpose, two tests were conducted--the clock test and the room test. The first test was in essence a perspective task, and the second test was a mental manipulation task. However, because both tests require conceptually difficult mental rotations, the authors refer to them both as mental rotation tests. (Contains 1 table and 4 figures.)
